Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Active Directory over LDAPS
Active Directory over LDAPS (Option C) is the correct solution because it encrypts authentication traffic using SSL/TLS, ensuring confidentiality. Option A is incorrect because local OS authentication does not use corporate credentials. Option B is incorrect because NTLM authentication is not supported as a direct identity source for vCenter Single Sign-On. Option D is incorrect because standard LDAP transmits credentials in plaintext, without encryption.
